Searching for Light Dark Matter and Dark Sectors with the NA64 experiment at the CERN SPS

Yu. M. Andreev, A. Antonov, M. Ayala-Torres, D. Banerjee et autres

Since its approval in 2016, NA64 has pioneered Light Dark Matter (LDM) searches with electron [1], positron [2], muon [3], and hadron [4] beams. The experiment has successfully met its primary objectives, as outlined in the EPPS input (2018), and even exceed …

Design and Characterization of the POKERINO Prototype for the POKER/NA64 Experiment at CERN

A. Antonov, P. Bisio, M. Bondí, A. Celentano et autres

The NA64 experiment at the CERN H4 beamline recently started a high-energy positron-beam program to search for light dark matter particles through a thick-target, missing-energy measurement. To fulfill the energy resolution requirement of the physics measurement σE/E≃2.5%/E[GeV]⊕0.5% and cope with the constraints …

Proof of principle for a light dark matter search with low-energy positron beams at NA64

Yu. M. Andreev, А. Антонов, M. Ayala-Torres, D. Banerjee et autres

A bstract Thermal light dark matter (LDM) with particle masses in the 1 MeV–1 GeV range could successfully explain the observed dark matter abundance as a relic from the primordial Universe. In this picture, a new feeble interaction acts as a “portal” …

High efficiency veto hadron calorimeter in the NA64 experiment at CERN

Yu. M. Andreev, A. Antonov, M. Ayala-Torres, D. Banerjee et autres

NA64 is a fixed-target experiment at the CERN SPS designed to search for Light particle Dark Matter (LDM) candidates with masses in the sub-GeV range. During the 2016-2022 runs, the experiment obtained the world-leading constraints, leaving however part of the well-motivated region …

Dark matter search in a Beam-Dump eXperiment (BDX) at Jefferson Lab: an update on PR12-16-001

M. Battaglieri, A. Bersani, G. Bracco, B. Caiffi et autres

This document is an update to the proposal PR12-16-001 Dark matter search in a Beam-Dump eXperiment (BDX) at Jefferson Lab submitted to JLab-PAC44 in 2016 reporting progress in addressing questions raised regarding the beam-on backgrounds. The concerns are addressed by adopting a …
